Many of the methods have some precincts because of the low adsorption capacity, poor integrity and need for pre-treatment. Aim: To evaluate the efficacy of three natural, low-cost, household-level products to remove fluoride from standard water. Materials and Methods: In this in vitro study, a standard solution of fluoride and a known weight of tulsi leaves, drumstick leaves and tamarind seed powder was prepared and analysed for changes in fluoride level and pH level on treatment at baseline, after 6 h and after 24 h. Results: Amongst the three plants, Tamarindus indica was found to be more effective in defluoridation showing a reduction up to 0.18 parts per million. Conclusion: Amongst the aforementioned three plants, tamarind seed powder was the domestic material with the best defluoridation property.
